The teams I've loved working on make the best use of what people are good at doing.

The people that need to "get together" to share untested ideas so they can make a decision, or share analysis to provide evidence of the validity of a plan will do so without the engineers that do the work. There has to be someone there that has an idea of engineering or architecture, but not the whole team.

In other words, even just a product manager and a CTO or architect can figure out what needs done while not knowing the details of how it will be done, but then they'll pass that information on to the implementation team. Individuals are paid to figure out how and to execute on that.
